Description
Thus state describes reference conditions. Refer to phase 1.1 for more information.
Submodel
Description
This state occurs where prolonged continuous grazing and lack of fire have led to a rubust tree overstory and a grass community dominated by warm-season perennials. Tree cover ranges from 20 to 40 percent.
Mechanism
Season-long grazing providing little rest and recovery for preferred grazed plants during critical growing periods, coupled with high utilization. Lack of fire is an additional mechanism here.
Mechanism
Fire/brush control coupled with a prolonged period of prescribed/deferred grazing. Seeding may also be required.
